As shown in these drawings, the electrical and electronic device 1 according to the present invention is coupled to the casing 10, the base bracket 15 seated on the casing 10, and the top of the base bracket 15. The printed circuit board 20, the mounting parts 21 and 16 formed on the printed circuit board 20 and the base bracket 15, respectively, and the mounting parts 21 and 16 are fastened to the printed circuit board 20. And the base bracket 15, the first electromagnetic wave reducing member 25 for grounding electromagnetic waves from the printed circuit board 20, one side of which is mounted to the printed circuit board 20, and the other side of the base bracket 15. And a second electromagnetic wave reducing member 30 made of a metal material to be elastically contacted with and to be provided at a position spaced apart from the first electromagnetic wave reducing member 25 to reduce electromagnetic waves.

케이싱(10)은 베이스브래킷(15) 및 인쇄회로기판(20)을 수용하여 베이스브래킷(15) 및 인쇄회로기판(20)을 외부의 충격으로부터 보호한다. The casing 10 accommodates the base bracket 15 and the printed circuit board 20 to protect the base bracket 15 and the printed circuit board 20 from external impact.

베이스브래킷(15)은 인쇄회로기판(20) 등으로부터 발생하는 전자파가 다른 부품에 전해지는 것을 방지하는 기능을 한다. 여기서, 베이스브래킷(15)은 일반적으로 도체로 마련되어 케이싱(10)을 통해 접지됨으써, EMI(Electro Magnetic Interference)가 방사되는 것을 줄일 수 있다. 베이스브래킷(15)의 판면에는 제1전자파저감부재(25)가 인쇄회로기판(20)의 마운팅부(21)를 통과한 후 체결되도록 체결공(17)이 형성된 마운팅부(16)가 돌출되어 있다. The base bracket 15 functions to prevent electromagnetic waves generated from the printed circuit board 20 or the like from being transmitted to other components. Here, the base bracket 15 is generally provided as a conductor and grounded through the casing 10, thereby reducing the emission of Electro Magnetic Interference (EMI). On the plate surface of the base bracket 15, the mounting portion 16 having the fastening hole 17 is protruded so that the first electromagnetic wave reduction member 25 passes through the mounting portion 21 of the printed circuit board 20. have.

인쇄회로기판(20)은 그 판면에 배선이 인쇄되고, 전자부품(칩, 22)이 실장되어 전기적 시스템(Electronic System)의 각종 보드로도 광범위하게 사용되며, 반도체 소자와 함께 전기적 시스템을 구성한다. 이러한 인쇄회로기판(20)은 전도나 방사 등에 의해 다른 부품에 불필요한 전자파를 발생하여, 다른 부품의 작동에 장애를 주게 된다. The printed circuit board 20 has wiring printed on its surface, and electronic components (chips) 22 mounted thereon, which are widely used as various boards of an electronic system, and together with semiconductor elements, constitute an electrical system. . The printed circuit board 20 generates unnecessary electromagnetic waves to other parts by conduction or radiation, thereby impeding the operation of other parts.

인쇄회로기판(20)의 마운팅부(21)는 IC(Integrated Circuit) 밀집영역과 간섭되는 것을 방지하기 위해 인쇄회로기판(20)의 각 모서리영역에 관통 형성되어 제1전자파저감부재가 각 마운팅부(21)에 장착되는 것이 바람직하다. 이에, 인쇄회로기판(20)의 배선 인쇄시 종래에 비해 복잡하지 않으므로 인쇄회로기판(20)의 설계를 용이하게 할 수 있다.The mounting part 21 of the printed circuit board 20 is formed through each corner area of the printed circuit board 20 to prevent interference with the integrated circuit (IC) dense area so that the first electromagnetic shield member is mounted on each mounting part. It is preferable to attach to (21). As a result, since the wiring printing of the printed circuit board 20 is not complicated compared with the related art, the design of the printed circuit board 20 can be facilitated.

제1전자파저감부재(25)는 인쇄회로기판(20)의 마운팅부(21)를 관통한 후 베이스브래킷(15)의 체결공(17)에 체결된다. 따라서, 제1전자파저감부재(25)는 인쇄회로기판(20)으로부터 발생하는 전자파를 베이스브래킷(15) 통해 접지시킴으로써 EMI가 방사되는 것을 줄일 수 있다. 여기서, 제1전자파저감부재(25)는 인쇄회로기 판(20)과 베이스브래킷(15)의 각 마운팅부(21, 16)에 체결되고, 금속재질로 마련된 스크류(25)인 것이 바람직하다. 이에, 인쇄회로기판(20)으로부터 발생된 전자파가 스크류(25)를 통해 베이스브래킷(15)에 전도되어 접지될 수 있다. The first electromagnetic wave sensing member 25 passes through the mounting portion 21 of the printed circuit board 20 and then is fastened to the fastening hole 17 of the base bracket 15. Therefore, the first electromagnetic wave reduction member 25 may reduce the EMI radiation by grounding the electromagnetic waves generated from the printed circuit board 20 through the base bracket 15. Here, the first electromagnetic wave reducing member 25 is fastened to the mounting portions 21 and 16 of the printed circuit board 20 and the base bracket 15, and preferably, the screw 25 is formed of a metal material. Thus, electromagnetic waves generated from the printed circuit board 20 may be conducted to the base bracket 15 through the screw 25 and grounded.

제2전자파저감부재(30)는 인쇄회로기판(20)의 배면과 베이스브래킷(15)의 상면에 접촉됨으로써, 제1전자파저감부재(25)와 더불어 인쇄회로기판(20)으로부터의 전자파의 방사를 저감시키는 기능을 한다. 전자파 방사를 줄이기 위해서는 인쇄회로기판(20)에서 발생하는 RF(Radio Frequency, 무선주파수) current loop를 줄여야 한다. 이를 위해, 인접한 스터드 포인트(stud point)의 거리가 최대 무선주파수파장(λ)/20인 것이 바람직하므로, 제2전자파저감부재(30)가 각 제1전자파저감부재(25)에서 무선주파수파장(λ)/20 정도 이격된 위치에 장착되는 것이 바람직하다. 여기서, 스터드 포인트(40)는 제2전자파저감부재 장착영역(23) 또는 스크류(25)가 체결되는 마운팅부(21)이다. The second electromagnetic wave reduction member 30 is in contact with the back surface of the printed circuit board 20 and the upper surface of the base bracket 15, thereby radiating electromagnetic waves from the printed circuit board 20 together with the first electromagnetic wave reduction member 25. It serves to reduce. In order to reduce electromagnetic radiation, the RF (Radio Frequency, radio frequency) current loop generated from the printed circuit board 20 should be reduced. To this end, it is preferable that the distance of the adjacent stud point is the maximum radio frequency wavelength lambda / 20, so that the second electromagnetic wave reduction member 30 has a radio frequency wavelength at each first electromagnetic wave reduction member 25. It is preferable to be mounted at a position spaced by? / 20. Here, the stud point 40 is a mounting portion 21 to which the second electromagnetic wave suppressing member mounting region 23 or the screw 25 is fastened.

제2전자파저감부재(30)는 인쇄회로기판(20)에 장착되는 장착부(31)와, 베이스브래킷(15)에 접촉되는 접촉부(32)와, 장착부(31) 및 접촉부(32)와 연결되어 인쇄회로기판(20)이 베이스브래킷(15)과 결합될 때 압축되는 탄성부(33)를 포함한다. The second electromagnetic wave reduction member 30 is connected to the mounting portion 31 mounted on the printed circuit board 20, the contact portion 32 contacting the base bracket 15, the mounting portion 31 and the contact portion 32. The printed circuit board 20 includes an elastic part 33 that is compressed when the printed circuit board 20 is coupled to the base bracket 15.

여기서, 제2전자파저감부재(30)는 인쇄회로기판(20)의 저면에 솔더링(일명, 납땜이라 함) 결합되는 것이 바람직하다. 즉, 작업자는 인쇄회로기판(20)의 저면에 솔더링을 한 후, 제2전자파저감부재(30)의 장착부(31)를 솔더링 영역에 안착시킴으로써 인쇄회로기판(20)에 제2전자파저감부재(30)를 결합시킬 수 있다. 제2전자파저감부재(30)의 높이는 인쇄회로기판(20)과 베이스브래킷(15) 사이의 공간보다 크게 제작되어 인쇄회로기판(20)이 베이스브래킷(15)에 스크류(25) 결합될 때 탄성부(33)가 압축되어야 한다. 이에, 인쇄회로기판(20)과 베이스브래킷(15)이 밀착 결합되기 때문에, 인쇄회로기판(20)에서 발생된 전자파가 베이스브래킷(15)에 잘 전도되어 접지될 수 있다.Here, it is preferable that the second electromagnetic wave reduction member 30 is soldered to the bottom surface of the printed circuit board 20 (also called soldering). That is, the operator solders the bottom surface of the printed circuit board 20, and then mounts the mounting portion 31 of the second electromagnetic wave reduction member 30 in the soldering area so that the second electromagnetic wave reduction member ( 30) can be combined. The height of the second electromagnetic wave reduction member 30 is greater than the space between the printed circuit board 20 and the base bracket 15 so that the printed circuit board 20 is elastic when the screw 25 is coupled to the base bracket 15. Part 33 should be compressed. Thus, since the printed circuit board 20 and the base bracket 15 are closely coupled, electromagnetic waves generated from the printed circuit board 20 may be well conducted to the base bracket 15 and grounded.

또한, 제2전자파저감부재(30)는 거의 'S'자 형상을 가지며, 일체로 형성된 것이 바람직하다. 여기서, 탄성부(33)는 장착부(31) 및 접촉부(32)의 각 단부로부터 한 회 절곡 형성되었으나 수회 절곡된 형상으로 마련될 수도 있으며, 형상은 이에 한정되지 않고 탄성력을 제공할 수 있는 범위 내에서 다양하게 변화될 수 있다. In addition, the second electromagnetic wave reduction member 30 has a substantially 'S' shape, it is preferable that it is formed integrally. Here, the elastic portion 33 is bent once from each end of the mounting portion 31 and the contact portion 32, but may be provided in a bent shape several times, the shape is not limited to this within the range that can provide an elastic force It can be changed in various ways.

전술한 실시예에서는, 탄성부가 장착부 및 접촉부와 일체 성형되나, 탄성부가 스프링으로 마련되어 장착부 및 접촉부와 일체 결합될 수도 있음은 물론이다.In the above-described embodiment, the elastic portion is integrally molded with the mounting portion and the contact portion, but the elastic portion may be provided as a spring and integrally coupled with the mounting portion and the contact portion.

이상 설명한 바와 같이, 본 발명에 따르면, 인쇄회로기판 설계시 배선인쇄가 용이하며 전자파를 효율적으로 저감시킬 수 있는 전기전자기기가 제공된다. As described above, according to the present invention, there is provided an electric and electronic device that can easily print wiring and efficiently reduce electromagnetic waves when designing a printed circuit board.
